ABSTRACT:
A method and apparatus is disclosed for synthesizing a fuel flow and a metering valve position used in a fuel control system of a turbomachine. Various construction details have been developed which provide a method to manipulate conventional turbine engine parameters to generate a synthesized fuel flow signal and metering valve position signal. In one embodiment, a synthesis means includes means to sense temperature, pressure and high pressure shaft speed, and means to manipulate the sensed signals to generate a synthesized fuel flow. A function generator responds to the synthesized fuel flow signal to generate a synthesized metering valve position signal.
